WIND-ENGINE.

SPECIFICATION forming part of Letters Patent No. 240,366, dated April19, 1881.

Application filed September 9, 1880. (No model.)

To all whom it may concern:

Be it known that I, GEORGE W. BEVARD, of Alexandria, in the county ofLicking, and in the State of Ohio, have invented certain new and usefulImprovements in Wind-Engines; and I do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings, and to the letters of reference markedthereon, making a part of this specitication.

This invention relates to certain improvements in windmills orwind-engines; and it has for its objects to increase the capacity andsimplify the construction of such mills or engines and the gearingwherebypoweris transmitted from the engine to the machinery to bedriven, and also to regulate the speed and.

power of the wind or driving wheel, as more fully hereinafter specified.These objects I attain by the apparatus illustrated in the accompanyingdrawings, in which- Figure 1 represents a side elevation of my Fig. 2represents a horizontal section through the windwheel; Fig. 3, avertical section of the mill or engine; and Fig. 4, a detached view,showing the mechanism by means of which the gates are opened and closedor controlled to regulate the admission of the wind to the wheel.

The letter A indicates an annular casing, open at its periphery and atits center, and mounted upon uprights B, rising from and supported upona suitable base, 0. The said casin g, atits center, is provided withupwardly and downwardly extending flanges D, the opening at the centerof the annular casing, with the said flanges, forming a cylindricalchamber, in which is located the wind or driving wheel E. The said wheelis mounted upon a vertical shaft, F, journaled at its lower end in abearing, G, on the base of the apparatus, and at its upperend in abearing, H, in a crossbar, I, secured to the upper flange D. The saidwheel is constructed of a disk, K, having secured to its opposite sidesa series of curved blades, L, extending radially from a circular flange,M, to the periphery of the disk. The said wheel is so located in itschamber that the upper and lower halves of the curved blades at therespective sides of the disk will extend into the portions of thewheel-chamber formed by the flanges D, while the intermediate portion ofthe wheel will lie in that part of the wheel-chamber formed by the spaceat the center of the annular casing, so that the wind, enterin g at theperiphery of the casin g, will strike the said intermediate portion ofthe Wheel at its periphery, and will find its escape at the oppositesides of the wheel from between the blades, causing the wheel to rotatein its course.

In the annular casing a series of gates, N, are pivoted at pointsindicated by the letter 0. These gates are tangential to the casing, andeach is provided at the bottom with a flange, P, the respective flangesbeing connected, by means of screws or pins Q passing through aperturesR i n the bottom of the casing, with a series of rods, T, which arepivoted at the points 'U to an annulus, V, surrounding loosely the lowerflange D, and supported and held in place at its periphery by means offlanged friction-rollers W, but at the same time permitted to turnfreely, so as to open or close the gates and regulate the admission ofwind to the wheels or cut it off entirely.

The letter A indicates a vertical shaft, stepped in a bearing, B, at thebase of the machine, and journaledat its upper end in a bearin g in across-bar, 0, located between two of the supporting-standards of theannular casing. The said shaft is hollow, and is provided with slottedlugs D, in which are pivoted arms E, carrying governor-balls F at theirlower ends. The upper ends of said arms are bent inward and bear againsta shoulder on a loose shaft, Gr, setting in the upper part of the shaftA, the upper end of said shaft G being provided with a collar, H, towhich is connected one end of a lever, l, fulcrumed in bearings K, theother end of said lever extending upward and Working looselyin abracket, L, projecting from the periphery of the annulus, so that whenthe lever is operated the annulus will be rotated slightly in onedirection or the other, thus opening or closing the gates to a greateror less extent. The shaft A has mounted on it a horizontal groovedwheel, M, which connects with a groove, N, or grooved pulley on the mainvertical shaft and trans mits motion from said shaft to the groovedWheel. Thislast-mentionedmechanism,itwill be seen, operates similarly toan ordinary engine-governor, and by regulating theopening of the gatesaccording to the speed of the wind-wheel secures a uniform motionthereto.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-'- The combination, in a Wind mill or engine, ofan annular casing having.upward anddownward flanges at its center, and adouble wind-whed located in the chamber formed by said flanges and thespace at the center of the casing, and a series of pivoted gates mountedin the casing, with mechanism for operating the same simultaneously,substantially as specified.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 19th day of August, 1880.
